Viewing aid



My viewing aid is characterized by an oval area containing a pattern comprising concentric circular contours. My viewing aid is further characterized by a rim of rectangular cross section abutting said oval area. My viewing aid is further characterized by a linear portion of cylindrical cross section separated from said oval area by a rectangular gap.
